To @ZZ whom it manueel/warn:

Be it known that I,-IIoMER K. STocKwnLL, a citizen of Canada, residing at Onaway, in the county of Presque Isle and State of Michigan, have invented new and useful Improvements in Machines for rTurning and Boring Articles, such as Spools, Sac. of which the following is a specification. Y

.This invention relates to certain improvements in machines for forming small woodenv articles, such as s ools, pail-handles, &c. y One object of t 's invention is. to provide an automatic machine for producing such ar- ,ticles as above mentioned.

e Anotherobject isto provide a machine that will shape the peri hery of an article and at the'same tim through.

Another object is to provide a machine of simple, cheap, and substantial construction for accomplishing the above objects.

- These objects I attain ,byv the means illustrated in the accompanying drawings, inv

whichv Figure 1 is a plan view of my machine, the ends being broken oil. Fig. 2-is a side elevation. Fig. 3 is a cross-section on the line 3 34 of Fig. 1. Fig. 4 is a detail plan view ofthe blade. Fig. 6 is a view of the feed-slide.;

Fig. 7 is a longitudinal section through one of 18, side bars 19, end bars 20, and cross-bars 21 21. The top 1 6 is provided with longitudinal guideways 22 and avcross-guideway 23.

i -''.i In the longitudinal guideways 22 are the slides 24, same slides carrying-suitable bearings 25, which support the tubular shaft 26,

adapted to revolve and slide therein.l The ends of the tubularshafts nearest the center of themachine are, reduced in diameter and screw-threaded, as at 27, to receive the skeleton chuck-heads 28,- provided with workholding nuts or noses 29, having serrated faces and a central aperture 30. To the opposite ends of the'tubular shafts are secured collars ore a hole there- Fig. 5 isa .view of a forming-v 31, betweenwhich ,are the-loose collars 32, provided with trunnions having bearings in the upper ends of the levers 23, pivotedto the cross-bars 21 by means of the pivot-bracket 34, adjustably secured to said cross bars. The levers 33 are slotted, as shown at 35, for the purpose of adjustment of the pivot. The lower ends of the levers33 are provided with rollers 36, which play in cam-grrooves 37 of the cam-wheels 38. By these means the tubular shafts are reciprocated back and forth. The tubular shafts are also provided with pulleys 39, whereby they are revolved through the means of a belt to a suitable'power-shaft. (N ot shown.) y

40 designates a bit-holder provided at one end with a recess'41 for the reception of the boring-tool 42. At the other end it is provided with an enlargedsection 43, square in cross-section, and a screw-threaded recess 44. The squared ends are. supported bysuitable bearings' 45, secured to the slides 24 and adapted to reciprocate therein. I

46 designates the threaded bars in thev nions on the upper ends of .the evers 49 which are pivoted at 50 to pivoted brackets 5 1, adjustably secured in the cross-bars 21. The lower ends of the levers 49 are provided with rollers 52, which play in cam-grooves 53 in the cam-wheels 54. f l

vThe cam-wheels 38 and cam-wheels 54 are secured to a counter-shaft 55, running longitudinally of the machine and adapted to be operated-in any suitable manner.

In the guideway 23 is adapted to reciprocate a-slide 56, having a tool-holderl57 and a pair of grasping springs or iingers 58, secured thereon. A tab e 59, supporting a feedchute 60,` is secured to the main frame at each side of the guide 56. The feed-chute is slotted on the front side and near its to is pivoted an escapement 61, operated by t e rods 62, pivotally secured to bearings mounted upon the slide. A plate-63 is secured tothe front end of the slide 56, to which is pivotally secured one end of a bar 64, the other end thereof being pivoted to the upper end'of a lever 65, pivoted at 66 tothe main frame. The lower end of the lever is pivoted to an arm 67, secured to an eccentric 68, mounted A upon the counter-shaft 55. The connection IOO between the eccentric arm and the lower end of the lever can be adjusted as desired. The feed-chute is automatically fed with material by the conveyer-belt 69, leading from a saw-table 70.

The operation is as follows: Suitable strips or bars of wood are fed against the saw, the sawed blocks being pushed upon the conveyerbelt and fed to the feed-chute, one finger of the escapement holding the ile until the crossslide moves forward. T e forward movement of the slide operates the escapement, one finger thereof releasing one block and the otherfinger of the escapement bylateral pressure against the bottom block of the pile holding the remainder of the pile until the crossslide returns to its initial position. At this time the grasping-fingers grasp the released block and on the forward movement of the cross-slide carry it between the centers of chucks or chuck-heads. Just as the block reaches the center of the machine the bits are advanced slightly by their cams enough to impinge the ends of the block, holding it until the grasping-fingers recede therefrom. At this time the chuck-heads advance, impinging the ends of the block, and it begins turning immediately. During. these movements the forming-tool is advancing, and at the same time one of the bits is advanced by its cam until it penetrates slightly beyond the'center of block and then recedes. As it recedes the other bit advances from the other side and nishes the boring. When finished, the chucks open and the finished product drops through the aperture in the center of the table and cross-slide. The reason for centering the block by the bits is to give a sufficient time for the grasping-fingers to be released; otherwise should the chuck impinge the block first it immediately commences to turn and would be likely to damage the grasping-fingers. The reason for advancing one bit before the other and only boring a little over half-way through is for the purpose of saving time, and the capacity of the machine is doubled thereby. Then the boring is being done, the grasping-fingers are advancing with another block.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l, The combination with a blank-feed, of a reciprocating means for gripping a blank and conveying it to a point in line with a nonrotating boring-bit, said bit and means for advancing the same to center and then bore the blank, and rotating gripping devices concentric with said bit, and means for advancing them to grip the work, subsequently to the boring-bit, and to rotate it during the boring advance of the bit and a reciprocating cutter, which advances to the blank during its rotation.

2. The combination with a feed -hopper and an escapement for discharging the blanks singly, of a reciprocating means for gripping a blank and conveying 1t to a point in line with a non-rotating boring-bit, said bit and means for advancing the same to center and then bore the blank, and rotating gripping devices concentric with said bit, and means for advancing them to grip the work, subsequently to the boring-bit, and to rotate it during the boring advance of the bit, and a reciprocating cutter which advances to the blank durin its rotation.

3. The combination with a blank-feed, of a reciprocating slide having means for gripping a blank and conveying it to a point 1n line with a non-rotating boring-bit, said bit and means for advancing the same to center and then bore the blank and rotating gripping devices concentric with said bit, and means for advancing them to grip the work, subsequently to the boring-bit, and to rotate it during the boring advance o1 the bit and a reciprocating cutter which advances to the blank during its rotation.

4. The combination with a blank-feed, of a reciprocating means for gripping a blank and conveying it to a point in line with two nonrotating boring-bits, said bits and means for advancing the same to center and then bore the blank, and rotating gripping devices concentric with said bits, and means for advancing them to grip the work subse uently to the boring-bit, and to rotate it uring the boring advance of the bits, and a reciprocating cutter which advances to the blank during its rotation.

5. The combination 'with a blank-feed, of a reciprocating means for gripping a blank and conveying it to a point in line with two nonrotating boring-bits, said bits and means for advancing the saine, first simultaneously an equal distance to center the blank, and thon alternately to bore vthe blank, and rotating gripping devices concentric with said bits, and means foradvancing them to grip the work subsequently to the boring-bits and to rotate it during the boring advance `of the bits, and a reciprocating cutter which advances to the blank during its rotation,

In testimony whereof I affix my signature in presence of two subscribing witnesses.
